Cyclohedron
In geometry, the cyclohedron or Bott–Taubes polytope is a certain (''n'' − 1)-dimensional polytope that is useful in studying knot invariants. The configuration space of ''n'' distinct points on the circle ''S''1 is an ''n''-dimensional manifold, which can be compactified into a manifold with corners by allowing the points to approach each other. This compactification can be factored as , where ''Wn'' is the cyclohedron. ==See also==
